Anisotropic Cube is a modification of my Gear Cube that is being sold by Mefferts.com. Buy a Gear Cube and replace four of the gearing edges by these four pieces. The result is a puzzle that has all the gearing fun of Gear Cube, but much harder to solve.

After stickers arrived from Dr. Sticker, I noticed that the PDF specified one white side, suitable for a black cube. I had to order one more side from Dr. Sticker in a new order to get one black side, suitable for a white cube.

Please kindly post one more PDF and please kindly designate them in the links, one PDF suitable for a black cube and one PDF suitable for a white cube.

(By the way I prefer black cubes, but that preference is irrelevant in this case. I own 2 black ones and 3 white ones, and bought white pieces from Shapeways, so my mod is white.)
